FLOOR FOR KILNS Filed June 3. 1929 Summer VERNON O. PATTON attorney 5Patented Feb. 17, 1931 UNITED STATES VERNON o. PATTON, OF NEW LEXINGTON,onro V FLOOR FOR KILNS Application filed June 3, 1929. Serial N'o.v368,098.

Tile floors of brick kilns as heretofore commonly constructed buckleupward. This buckling is caused by the fact that dirt and sandaccumulates in the spaces between the 5 'Jile and the floor uponexpanding due to the heat of the kiln, buckles upward. At first thisbuckling may be slight but repeated buckling widens the spaces betweenthe tile so that they receive more and more dirt and up, dirt removedand the floor laid anew.

The object of this invention is to provide an improved kiln floor andmember therefor in which the dirt and sand deposited on the floorescapes from the spaces between the tile so that the tile are free toexpand from their normal position without impedence by sand, dirt orother impeding means between them. The invention is embodied in theexample herein shown and described, the features of novelty beingfinally claimed.

in the accompanying drawing- Figure 1 is a perspective view of a tileincluded in the construction according to my invention.

Fig. 2 illustrates a portion of kiln including a floor according to theinvention, the tile being on a smaller scale than in Fig. 1.

In the views 5 designates the body of the tile which is of fire clay andgenerally speaking is rectangular or oblong and has near the middle ofone of its vertical faces a groove 6 expanded downward. At the top ofthe tile is a rectangular upward projection 6 locat- K ed near themiddle of the groove, said projoction having one vertical facecoinciding with the face of the groove and its other face coincidingwith the opposite face of the block.

Referring now to Fig. 2 the characters 7 represent ridges parallel toone another to a common level at the top, these ridges being built ofbrick on the ground. The spaces between the ridges form lines for thepassage of heat and products of combustion to the fiues. The tilesaccording to Fig. 1 are first laid as shown in rows on the ridges asshown in Fig. 2, the ends of the tiles resting on the ridges andbridging the fines. On the adj a- 0 cent ends of the tile and in thespaces between :;and until finally the floor must be taken the rows ofthe tile projections 6 are placed rectangular slabs 8 of the samematerial as the tile, said slabs being of such thickness that when laidon ribbons of mortar 9 their upper faces are substantially level withthe upper faces of the projections 6*. Said slabs are made of suchdimensions that they loosely occupy the spaces indicated and so as toallow for normal expansion by the kiln heat.

It will be observed that by reason of the ample spaces afforded betweenthe members and at the expanded grooves of the tile composing the floorthe sand and dirt dribbles down into the flues between ridges and may beeasily removed from time to time.

The forms of the parts can be changed without departing from the gist ofthe invention as claimed.

.VVhat I claim is: V

1. A floor for a kiln including rows of tile blocks each having ahorizontal upper face and an upward projection from said upperhorizontal face of less width than the length of said horizontal faceand on said upper horizontal faces and slabs laid on said tile blockbetween said rows of projections.

2. A floor for a kiln including rows of tile some of which have a groovein their vertical faces and a projection from their upper faces, andslabs with a horizontal flat face thereof laid on said tile between saidrows of projections.

3. A floor for a kiln including rows of tile some of which have adownwardly expanded groove in their vertical faces and a projection fromtheir upper faces substantially coinciding with said groove, and slabseach with a horizontal flat face laid at each face on said tile betweensaid rows of projections.

l. A floor for a kiln including a tile having a groove in one of itsvertical faces, its upper face substantially horizontal and a projectionfrom said upper face having one ofits vertical faces substantiallycoinciding with the face of the groove.

5. A floor for a kiln including parallel ridges, parallel rows of tilesupported on said ridges, said tile having upward projections and slabslaid on said tile between said rows of projections and over the tops ofthe spaces between the parallel rows of tile.

6. A floor for a kiln including parallel ridges, parallel rows of tilesupported on said ridges, said tile having upward projections and slabslaid on said tile between said rows of projections over the tops of thespaces between the parallel rows of tile and indirectly supported bysaid ridges.

7. As an article of manufacture a tile member for a kiln floor, saidtile member having vertical faces and a horizontal upper face having aprojection therefrom, one of said vertical faces provided with a groovesaid upper face at the side of said projection forming a horizontalsupport for a slab to constitute a part of the kiln floor.

8. As an article of manufacture a tile memher for a kiln floor, saidtile member having vertical faces and a horizontal upper face, one ofsaid vertical faces provided with a groove and the upper horizontal facepro vided with a projection therefrom having one of its faces coincidingwih the groove, said upper face of the slab at the side of theprojection forming a horizontal support for a slab constituting a partof the kiln floor.

9. As an article of manufacture a tile member for a kiln floor, saidtile member having vertical faces and a horizontal upper face, one ofsaid vertical faces provided with a groove flaring downward, and theupper horizontal face provided with a projection therefrom having one ofits faces coinciding with the said vertical groove, said upperhorizontal face of the tile at each side of said projection constitutinga horizontal support for a slab to form a part of the kiln floor.
